That was simply a user input error, as there are no zero ohm resistor, certainly not a room temperature. Put in the real resistance values and it will work.
Lefty! I took a picture of two of them so you wouldn't say that they didn't exist!
You mean the color code is wrong?
wanna borrow my milliohm meter? you can measure the resistance of pure copper wire with them =)
so he is right, there is no such thing as a zero ohm resistor at room temperature, its resistance is just so freaking tiny it doesnt matter for 99.99999% of applications
